The Futaba 10C radio (non-module version) is [Tom]’s transmitter of choice. Unfortunately, it isn’t compatible with the Spektrum DSM2 technology modules he wanted to use. So, being the crafty guy he is, he decided to hack it so it was.

Upon opening the Futaba transmitter, he realized that the non-module version of the 10C didn’t really seem that different than a module version. His transmitter just has a pcb hardwired in place where the modules would otherwise go. He soldered a 4 conductor audio jack to the unused pins on the pcb in the transmitter, then mounted it in the case with some J.B. Weld. He then wired and mounted the receiving jack in the module case. A small 6 inch audio cable bridges the two devices, and velcro holds them neatly together.

He discovered that certain modules have problems with the channels being out of order. Unless someone comes up with a firmware hack, there’s no way to remap the controls. So, some modules are just not compatible. [Tom] gives a very nice video walkthrough after the break. Check it out.
